A 28-year-old woman undertaking in vitro fertilisation had a single day five blastocyst transferred, resulting in a monozygotic triplet pregnancy. This case report illustrates the potential for multiple pregnancies even after transfer of a single embryo. A literature review regarding monozygotic triplets following use of assisted reproductive techniques reveals that an unexpectedly large proportion of these cases are associated with blastocyst transfer.
